I am having an issue with the supplied DataPointSelectionModifier for the Polar Chart. The multiselect and drag function works properly.

However, I want to be able to also select a single point, or multiple singular points using the ctrl key + clicking on a point. This works for the X/Y chart, but not Polar. Could there be a setting I am missing?

Please let me know if this is enough information to go by, and the question is clear.

I attached two images of what I need to do (easier than explaining it), I’m interested in the blue polygon, It could resemble the use of columns with the polar chart, but not quite, is there a simple way to do this or could someone point me to the right direction?

This code gets mouse point coordinates, then it converts pixel coordinates to polar, and then (a,b) data are obtained with GetCurrentCoordinateCalculator().GetDataValue(), but a and b have some strange values. I’ve tried just the opposite (from data value to pixel coordinate using GetCoordinate()), but it still doesn’t work. Any ideas? Is it possible to get data from pixel coordinates in polar chart?

I am implementing polar chart in my wpf application, and I am trying to customize the next with no success: – Xaxis data range is between the lowest and the highest value. I need that xaxis goes from 0º to 360º, but sometimes my angle dataseries does not cover the whole range (i.e. it goes from 15º to 270º). I’ve tried a customtickprovider, setting VisibleRange from 0 to 360º, but it doesn’t work. Any ideas? – I need that the line connecting to points is a straight, but a curve is drawn instead. Is there any property in PolarXAxis or FastLineRenderableSeries to achieve this?

However as the OP on that question noted there are several drawbacks to simply rotating the entire chart surface. Also I found that at run-time rotating the chart surface is inaccurate as in this example:

As you can see the 100 degree mark is not in the correct location. Directly right should be 90.

I’m trying out polar chart for my specific needs. In my scenario x-axis needs to display 0-360 (angle) values starting from bottom and going counter-clockwise so that 0 is at the bottom, 90 is at right, 180 is at the top and so on. Looking at polar chart default x-axis display it starts from right and go clockwise. Is there any way to change this behavior?
